Electrical Characteristics
Absolute Maximum Ratings
Stresses greater than the Absolute Maximum Ratings listed in Table 36 may
cause permanent damage to the device. This rating is a stress rating only. Func-
tional operation of the device at any condition above those indicated in the opera-
tional sections of these specifications is not implied. Exposure to absolute
maximum rating conditions for an extended period may affect device reliability.

Notes:
1. Applies to all pins except Crystal pins and where otherwise noted.
2. There is no input protection diode from pin to V_DD and current into pin is limited to ±600 µA.
3. Excludes X_IN and X_OUT pins.
4. Device pin is not at an output Low state.

Total power dissipation should not exceed 1.21 W for the package. Power dissipa-
tion is calculated as follows:
Total Power Dissipation =
V_DD x [I_DD – (sum of I_OH),
+ sum of [(V_DD – V_OH) x I_OH]
+ sum of (V_OL x I_OL)
